Abstract

The ongoing Digital Terrestrial Television (DTT) switchover leads to an interesting opportunity for the implementation of advanced television services. Actually, these services can even be interactive, since it is foreseen that the required Set-Top Boxes (STB) could be equipped with an Internet connection. However, among the future clients of DTT there are a large number of elderly and visually impaired people who can not entirely benefit of these services due to their physical limitations. Nevertheless, considering that Interactive Television (iTV) services can contribute to improve life quality of this type of users, it is essential to apply accessibility, usability and design-oriented guidelines for their development. In this context, this paper introduces a research related to universal design applied to iTV, being its aim to propose an advanced and accessible audio description service. In order to perceive the visually impaired users’ problems and needs, a group of individuals was asked to participate in an interview.
